摘要
针对运动员起跑反应时与短跑成绩之间关系,选取了2011~2019年5届世界田径锦标赛短距离跑的运动员比赛数据,运用Pearson相关系数分析和独立样本非参数检验的方法进行实证研究。结果表明,仅女运动员100米跨栏的起跑反应时与运动成绩没有显著性相关,其余项目运动员的起跑反应时与短距离跑成绩均存在正相关关系;运动员的起跑反应时在性别上存在差异,并且男性运动员的反应时长略低于女性运动员;运动员起跑反应时分布仅2011年与2019年这两届世锦赛短距离比赛中显著不同;运动员在比赛项目上存在显著差异,在跨栏项目中的起跑反应时最短,在弯道项目中的起跑反应时最长。
Aiming at the relationship between athlete's starting reaction time and sprint performance,the competition data of sprint athletes from the five World Athletics Championships in 2011-2019 are selected,and Pearson correlation coefficient analysis and independent sample non-parametric test are used to conduct empirical research.Research shows that only female athletes'100-meter hurdles'starting reaction time is not significantly correlated with their athletic performance,while the other athletes'starting reaction times are positively correlated with sprint performances;athletes'starting reaction times are different in gender.And the reaction time of male athletes is slightly lower than that of female athletes;the starting reaction time distribution of athletes is only significantly different in the 2011 and 2019 two World Championships sprint competitions;athletes have significant differences in competition events,and the start in the hurdle event.The reaction time is the shortest,and the starting reaction time is the longest in the corner event.
